Here's a really rough WIP for the 4th level. It's the likely candidate for my route since I don't have to rely on tp through the walls a lot.
There is another route I'm debating where I start the level with full energy and use nothing but the topmost part of the level until the chasm to get past the barriers. The only problem with the route is the energy issue. Because I have to make 3 long teleports, it is required that I have a completely full energy meter by the time I get to the first long tp (at the iceman powerup). In order to do it this way, I have to drop down a few levels at the start of the level and smash a switch that will drop one of the barriers for me.
This is another lovely example of energy management at it's finest. If I take the route in that video (with some minor tweaking of the actual platforms I hit, etc etc) I get to the chasm at roughly the same time as the other route, although this one is more dangerous. If I use the topmost route, I waste time with the start of level barrier, but have less of a chance of losing health along the way (aside from the planes) and with some good timing can make up the lost time with well placed air attack spamming. The downside is of course that I will be at the bare minimum to make the last tp in the level with nothing left over. The other thing to take into consideration is I need almost a full charge at the start of mojo's level for all the tp's. Granted I haven't gotten the orb glitch to work perfectly for me yet, so it's looking like w/e route I can get done the fastest will be the one to use IF I can count on the orb glitch.
Oh we're not done yet, there's yet ANOTHER level to revisit, lvl 3. Apparently I've been sleeping on the job, cause Spider-Waffle found a lovely little tp trick that can save on waiting for the elevator in the second half of the level. He also figured out how to take Apocalypse down in only 3 hits. Combine these two together and it's a savings of almost 20 seconds.
After entering the second half of the level, I have to go up one floor, high jump then tp up through the floor. Then I have to get on a platform (w/o moving right otherwise I'll trigger the Juggernaut fight), switch to Cyclops, have him use his really high jump (he'll bump his head on the ceiling) and quickly switch to nightcrawler then tp up through the floor. Another way is to have nightcrawler do a high jump, then 2 small tp's straight up. For Apocalypse, Wolverine's spin attack will take him down in 3 hits (which rogue can be substituted for at least 1 hit if wolvy is too weak to take the shots).
However these are the drawbacks. 1) Doing the ele skip requires using more tp's which means more energy usage which ultimately means more time needed to recharge for lvl 4 (where energy is a really big concern). 2) If I use Cyclops to make the really high jump first, it'll save some energy with Night, but it means I can't use Wolvy against Apocalypse, so I'm limited to a 4 hit minimum fight (and Apoc wastes 4 seconds total from the time he becomes invuln to when you can actually hit him). So I can either use all my energy gettin to Apoc an use Wolvy to take the level down a lot faster, or wait for the ele and play it safe for the next level.
